VALVE-GUARD.

Specification of Letters Patent.

Patented July 6, 1909.

Application filed December 4, 1908. Serial No. 468,039.

T 0 all whom it may concern:

Be it known that I, WILLIAM THOMPSON, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Valve-Guards, of which the following is a specification.

This invention relates to improvements in valve guards.

My improvements are particularly applicable to the valves for gas stove burners, and I have illustrated the same herein embodied in a gas stove, although they are applicable and desirable for use in other relations.

The main object of this invention is to provide an improved valve guard for the valves of gas stoves and the like, which is quickly adjusted to prevent or permit the manipulation of the valves, and, when in its open position, is inconspicuous and unobtrusive.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.-

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined. and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a detail plan view of a structure embodying the features of my invention; Fig. 2 is a vertical cross section taken on a line corresponding to line 2-2 of Fig. 1, the valves being omitted, and the guard plate being indicated in. its closed or operative position by dotted lines; Fig. 3 is a vertical cross section taken on a line corresponding to line 33 of Fig. l, the uard plate being indicated in its open or inoperative position by dotted lines, the valve hand-piece being shown in full lines, and indicated in its open position by dotted lines; Fig. 4 is a detail sec tion through one of the supporting brackets for the manifold; Fig. 5 is a perspective view of one of the bracket-like hinge members for the guard plate.

In the drawings, similar reference numerals refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the manifold 1 is suitably connected to the gas supply, the

connection not being here illustrated. The manifold is supported by bracket-like members 2, which are here illustrated in conventional form. The valve casings 3 are preferably arranged on the inner sides of the manifold, the valves having upwardly-projecting stems 4 with hand-pieces 5, the hand-pieces being adapted to swing over the manifold in opening, as is shown by dotted lines in Fig. 3.

The guard plate is preferably provided with a longitudinal rib 7 at its outer edge, which is preferably formed by a curved o'l'lset, as illustrated, and with notches 8 at its inner edge adapted to receive the valve casings when the guard plate is in its closed or operative position. This longitudinal rib 7, when the guard is in its closed, or operative position, rests against the hand-pieces of the valve stems, thereby preventing the opening of the same.

The guard plate is pivotally and slidably supported by means of the hinge members 9 which have offsets 10 at their upper ends adapted to overhang the manifold and coact therewith to form the pivot bearings 11 and the vertical ways 12. These brackets are preferably supported by the bolts 13 arranged through the supporting brackets 2 for the manifold. The pivots 14 are preferably formed integral on the ends of the guard plate, being flattened in cross section so as to enter the ways 12 when presented cdgewise thereto, thereby permitting the guard plate to drop down in front of the valve stems, as illustrated in Fig. 3. This support for the plate also holds it in its closed, or operative position.

W hen the guard plate is in its open, or inoperative position, with the parts arranged as l have illustrated in the accompanying drawing, it rests upon the top of the manifold so that it entirely out of the way and does not detract from the appearance of the stove. Vvhen the guard plate is in its closed position, the valves are locked in their closed position. The advantages of this will be obvious, as it prevents the accidental opening of the valves, and also prevents their being opened by children, and, further,

l when the guard plate is in its closed position,

it insures the complete closing of the valves, and if any of the valves are partially opened, the closing of the guard plate will close them.

I have illustrated and described my improvements in detail in the form preferred by me on account of its structural simplicity and economy, and as applied to gas stoves, as I have embodied and made use of the same in that particular relation. Modifications in structural details, however, will readily appear to those skilled in the art to which this invention relates, and I have not, therefore, attempted to describe or point them out specifically herein.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a manifold, of a plurality of valve casings arranged on the inner side of said manifold; valves having upwardlyprojecting stems provided with hand pieces adapted to swing toward said manifold in opening; s pporting brackets for said manifold; a guard plate having an offset longitudinal rim at its outer edge and notches in its inner edge adapted to receive the said valve casings when said guard plate is in its closed position; flattened pivots for said guard plate; and a pair of bracket-like hinge members secured to said supporting brackets for said manifold, and coacting with the said manifold to form bearings for said pivots, and slot-lilre ways adapted to receive said pivots when presented edgewise thereto, whereby said guard plate is adapted to rest upon said manifold when in its open position and supported in its closed position to prevent the opening of said valves.

2. The combination with a manifold, of a plurality of valve casings arranged on the inner side of said manifold; valves having uawardl nroieetin stems nrovided with handpieccs adapted to swing toward said manifold in opening; supporting brackets for said manifold; a guard plate; flattened pivots for said guard plate; and a pair of bracket like hinge members secured to said supporting brackets for said manifold, and coacting with the said manifold to form bearings for said pivots, and slot-like ways adapted to receive said pivots when presented edgewise thereto, whereby said guard plate is adapted to rest upon said manifold when in its open position and supported in its closed position to prevent the opening ofsaid valves.

The combination with a manifold, of a plurality of valve casings arranged on the inner side of said manifold; valves having upwardly-projecting stems provided with hand pieces adapted to swing toward said manifold in opening; a guard plate having an offset longitudinal rib at its outer edge and notches in its inner edge adapted to receive the said. valve casings when said guard plate is in its closed position; flattened pivots for said guard plate; and bearings for said pivots in which they are pivotally and slidably adjustable, whereby said guard plate is adapted to rest upon said manifold when in its open position and supported in its closed position to prevent the opening of said valves.

l. The combination with a manifold, of a plurality of valve casings arranged on the inner side of said manifold; valves having upwardly-projecting stems provided with hand pieces adapted to swing toward said manifold in opening; a guard plate; flattened pivots for said guard plate; and bearings for said pivots in which they are pivotally and slidably adjustable, whereby said guard plate is adapted to rest upon said manifold when in its open position and supported in closed position to prevent the opening of said valves.

5. The combination with a manifold, of a plurality of valve casings arranged on said manifold; valves having stems provided with hand pieces; a guard plate having an offset longitudinal rib at its outer edge and notches in its inner edge adapted to receive the said valves when said guard plate is in its closed position; supports for said guard plate whereby it is pivotally and slidably supported, all coacting for the purpose specified.

6. The combination with a manifold, of a plurality of valve casings arranged on said manifold; valves having stems provided with hand pieces; a guard plate; and supports for said guard plate whereby it is pivotally and slidably supported, all coacting for the purpose specified.

7. The combination with a gas supply member, of a valve casing projecting laterally therefrom; a valve having a stem provided with a projecting hand piece; and a guard mounted to be pivotally and slidably adjusted upon said supply member, all coacting for the purpose specified.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
